APPARATUS FOR SEPARATING MATTE FROM SLAG.

SPECIFICATION forming part of Letters Patent No. 489,307, dated January3, 1893. Application filed July 14, 1892- Serial No. 440,045. (Nomodel.)

To all whom it may concern.-

Be it known that 1, WILLIAM HENRY How- ARD,a subject of the Queen ofGreat Britain, at present residing at Pueblo, in the county of Puebloand State of Colorado, have invented a new and Improved Apparatus forSeparating Matte from Slag,of which the following is a full, clear, andexact description.

The object of the invention is to provide a new and improved apparatusforconveniently separating matte from slag in lead and copper smelting,at the same time deadening the flow of the matte and slag from thefurnace to the settler.

The invention consists of certain parts and details, and combinations ofthe same, as will be hereinafter described and then pointed out in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front view of the improvement as applied and with parts insection; Fig. 2 is a plan view of the apparatus; Fig. 3 is a transversesection of the same on the line 33 of Fig.2; and Fig. 4 is a sideelevation of the partition and its support.

The furnace A, of any approved construction is provided with the usualoutlet spout B, adapted to discharge the matte and slag into a settlerO, preferably mounted on wheels so as to be conveniently moved to andfrom the furnace to receive the charge. The settler O is in the shape ofan open pot and is provided on its front with a spout D, for carryingoff the matte settling in the bottom of the settler O, the said spoutdischarging in the usual mold E, also preferably mounted on wheels.

On the edge of the settler O and extending to the front is an outletspout F, for carrying off the slag which separates in the settler fromthe matte. In order to conveniently separate the slag, a partition G isemployed adapted to be supported in the settler and arranged to belifted off the same whenever the settler is moved away from the furnacefor cooling and other purposes. This partition G is provided at its endswithflanges G adapted to rest on the flanges of the settler O, as willbe of the partition receives the flow which is thus deadened beforepassing into the settler O.

The partition G is made hollow and contains a water pipe H, the ends Hand H of which extend outwardly and are connected with a flexible inletpipe I and a flexible outlet pipe I, of which the pipe I is connectedwith a suitable source of water supply and the pipe I leads to adischarge. The partition G is provided with links J, connected with aring K, held on the lower end of a cable or chain L, passing overpulleys N and N, journaled in a suitable support erected in front of thefurnace. A weight 0, is suspended from the other end of the cable so asto counterbalance the partition G. By this device the partition G can bereadily inserted in the top of the settler O, or removed therefrom bypulling on the weight 0. When not in use, the partition G is suspendedin front of the furnace but out of the way of the workmen.

The device is used as follows: The settler O is wheeled to the front ofthe furnace, and then the partition G is let down and seated in thesettler O, as described,so that the back of the partition extends acrossthe flow of the matte and slag passing from the spout B after thefurnace is tapped. The matte and slag are deflected downward into thesettler C after striking the partition so that the matte readily settlesin the bottom of the settler, while the slag flows to the other side ofthe parti tion and is discharged over the tapped outlet spout F. hensufficient matte has accumulated in the settler, the spout D is tappedin the usual manner to permit the matte to flow into the mold E heldbelow the said spout as shown in the drawings. As the settler O cannotwithstand the constant corrosive action of the matte for any length oftime without serious injury to the settler, it is necessary to removethe settler and use another one in place for the time being. Now,inorder to conveniently transfer the partition G from the first settler,the partition is raised as above described, the settler is removed and anew one inserted in place and then the partition 18 again lowered intothe second settler, and the above described operation is repeated forseparating the matte from the slag. When the material in the removedsettler has cooled sufficiently to permit of conveniently dumping thematerial and the latter has been accomplished, then the inside of thesettler is coated again with clay wash in the usual manner so as to beready for further use in the manner above described.

I am aware that fixed water cooled plates have been used in connectionwith fixed pots or settlers, but such I do not claim, as sucharrangement is found to be impracticable 0wing to the formation of cruston the inside of the pot, as that will render it impossible to tap thematte conveniently.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent,-

1. The combination,with the settler, of the Vertically movablepartition, the water pipe arranged within it, the flexible inlet andoutlet pipes connected with the partition pipe, and the cable, pulley,and counterbalance, all arranged as shown and described.

2. An apparatus for separating matte from slag, comprising a settler awater-cooled partition formed with flanges adapted to be seated on theedge of the settler, and means, substantially as described, forsupporting, counterbalancing, and raising and lowering the said jacket,substantially as shown and described.
